PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 772,576, dated October18, 1904.

Application filed March 7, 1903.

To whom it may concern.-

Be it known that I, JESSE D. NoY s, a citizen of the United States,residing at Shamburg, in the county of Venango and State ofPennsylvania, have invented a new and useful Improvement inPipe-Wrenches, of which the following is a specification.

My invention relates to wrenches used in connecting and disconnectingpipes in differing positions, as oil or gas pipes, where the wrench isrequired to be used in horizontal, vertical, or inclined positions, andthe pipes are of varying diameters, my object being to make a wrenchthat can be applied to pipes 'in all positions and :to many of thevarying sizes; in short, to makeone wrench do the work that hasheretofore required several; also, to provide a device by which thewrench may be locked on the pipe and left as long as desired. I attainthis end by the device as illustrated in the accompanying drawings, inwhich Figure 1 is a view of the wrench as applied to the pipe and alsoshowing in dotted lines the position of the partswith the jaws thrownopen, as when released from the pipe; Fig. 2, the same as Fig. l, butwith one side of the fork or handle removed to show the parts covered;and Fig. 3, a view of the ends of the jaws and handle to more clearlyshow the locking device.

In the several views the same parts are indicated by the same numerals.

' 1 is the handle or lever, the extension of the free end not beingshown. This lever is forked, as shown in Fig. 3, to pass on both sidesof the jaws 2 and 4.

2 is a jaw hinged to the lever by the pin 8. This jaw is shapedsubstantially as shown, and with a second jaw 4 hinged to it by the pin5. Both of the jaws pass between the sides of the fork on the lever 1and have free motion between the sides, except that the jaw 4' iscontrolled by a pin 6 in the handle moving in the groove 7 in the jaw.

8 represents the pipe on which thejaws are closed and gripping.

In Fig. 2 is shown-the shoulder 9 at the bottom of the fork of thehandle, which is fitted to bear against the under side of the jaw 4 inSerialNo. 146,722. (No model.)

allpositions and relieve the heavy strain which would otherwisecome uponthe pin 6. The pin is only useful in holding the jaw against theshoulder 9.

To lock the parts of the wrench in any desired position, either wideopen or against any size pipe, there is placed on one side of the handle1 a bolt 10, preferably inclosed, but shown in section in Fig. 2. Thisbolt is fitted to slide up and engage with recesses in the under side ofthe jaw 4, thus holding the jaw from sliding back and forth through thehandle, thus locking all parts of the wrench. This bolt is bent at thebottom 11 for convenience of work, and in the lower end of the case 10is the recess 12, fitted to receive the bent end 11. When adjusted toenter the recess 12, a spring 13 forces the bolt 10 up to engage withthe jaw 4 and lock the wrench. By drawing down the bolt and turning itto either side it is held back and leaves the wrench free.

The operation is as follows: The wrench, wide open, as shown by thedotted lines in Fig. 1, is placed around the pipe and the jaws closed,bringing the jaws 2 and 4 in contact with the pipe, and by pressure tothe left on the lever the serrated surfaces clutch the pipe firmly.Then, if desired, the bolt 10 is turned to the proper position and bythe action of the spring 13 is thrown up, engaging with the jaw 4. Thewrench is then securely fast on the pipe and may be left alone. Todisengage it, withdraw the bolt, turn the handle to one side of the slot12, when it is held back, the handle 1 moved to the right, and thewrench removed.

I claim as my invention- 1. A pipe-wrench; consisting of the handle orlever 1, forked as shown, and having hinged to it the jaw 2, with thejaw 4 hinged tothe jaw 2; 'both jaws playing through the fork in thelever, the jaw 4, resting against the bottom of the fork and beingcontrolled .by the pin 6, in one fork of the handle playing back andforthin the groove 7 in the jaw 4; all working in combinationsubstantially as shown and described.

2. A pipe-wrench; consisting of the forked handle 1, the jaws 2, and 4,formed and connected as shown, the jaw 4, bearing against the bottom ofthe fork and controlled by the pin 6, in the handle plying in the groove7 in the jaw 4, and With the locking device of the bolt 10, fitted toengage With the under side of the jaw 4; all the parts Working in combination as shown and for the purpose herein deserlbed.

In testimony whereof lhzive signed my name to this specification 1n thepresence of two suh- 1 scribing witnesses.
